The principle of column speaker
There are at least two speakers unit to be a column speaker,In a certain range of listening, the attenuation of sound
is much lower than the sound point.For example, 5M distance, point sound source of about 14dB, and a high quality column speaker only attenuated the 7 dB, because the following is a times the gap, so the distance is far more
obvious gap. In such a distance, the proportion of direct sound is beyond the sound of the reflection, the room or
the environment can greatly reduce the impact of the hearing.
The assortment of column speaker
1.According to if built in amplifier or not: active column speaker&passive column speaker
2.According to the application:Professional column speaker,home theater column speaker,multi media column speaker.
3.According to the material:aluminum column speaker,wooden column speaker,plastic column speaker.
General speaking, aluminum column speaker and wood column speaker are better than plastic column speaker, but
unless it is the high cost of paint processing, otherwise the appearance of wood sound column generally noteye-catching
is basically only low-grade multimedia basic products will by wood column speaker. Some of the professional use of the column speaker will also use the wooden material, but the general is the use of plywood, and spray paint treatment, the effect can be guaranteed. Because of the low shell strength, the general effect is poor.
